Twist-bend nematics and heliconical cholesterics: a physico-chemical analysis of phase transitions and related specific properties

Natalia Kasian, Longin Lisetski, Igor Gvozdovskyy

Certain nematic liquid crystals, e.g., those formed by banana-shaped molecules, can exhibit a low-temperature twist-bend nematic (Ntb) phase. Upon addition of chiral dopants, a chi…
